Examples of wide-based robots using traction and omni wheels

This seems interesting, but I don't see why it's any better than tractions in front and omnis in the back.

The benefit will lie in turning.

Your wording makes we want to test that right now. I think we'll possibly stick to using *gulp* Lunacy wheels. They fit our needs, and we'll be able to keep our bot the way it is without changing too much right now.

One thing that the team felt in 2010 (the video above) was a significant amount of fishtailing. With the wide base, perhaps you'll feel a significant amount of that compounded with increased sensitivity.

With the setup that PayneTrain has suggested, notice that there is no real point about which the robot can fish tail. It forges stability into a potentially unstable design all while distributing the weight over omni wheels and traction wheels.
